INVENTOR A TTORNEYS ALVIN EMIL CARLSON,

DISPENSING DEVICE.

Specification of Application filed October s, 1920. Serial N 0. 417,923.

To all whom it may concern:

Be it known that I, ALVIN E.-CARLsoN, a citizen of the United States, and resident of Nevis, in the county of Hubbard and State of Minnesota, have invented a new and Improved Dispensing Device, of which the following is a full, clear, and exact descri tion.

l y invention relates to a dispensing device, and aims to provide a fixture of this form, has been far greater than in the case where the same quantity of paper was furnished in roll form. Further, even paper in the form of a roll has proven expensive, in that it has been necessary to perforate the sheets of paper at predetermined lengths to permit of its detachment from the roll.

With this-in view, I have provideda dispensing machine adapted to furnish strips of material at predetermined lengths from a roll of such material.

A further object of my invention is the construction of a device of this nature-which shall be adapted to furnish strips of material as aforestated, from a roll of paper, it being unnecessary, however, toprovide perforations in the body of the roll to permit of the tearing of the strip ofpaper from the top of the same. I

A still further object of my invention is the construction of a dispensing device which shall automatically entirely detach the stripfrom the body of the roll.

Other objects of my invention are the provision of a machine of the type specified,

which shall be'extremely simple in construction and operation and hence economical in application and use.

Reference is had to the attached sheet of drawings as illustrating one practical embodiment of my invention, and in which Figure 1 is a sectional side view of a dispensing device constructed in accordance with my invention.

Fig. 2 is a fragmentary sectional side view of one of the elements of the machine.

F1g. 8 is a sectionalend View taken in the direction of the arrows and along the lines 3-3 of Fig.1, and I I Fig. 4 is a sectional view taken along the lines 4-4 of Fig. 3.

In these views the reference numeral 5 indicates the casing of any desirable contour, and which may be conveniently provided with an opening 6 through which the strips of paper may be dispensed.

A pair of shafts, 7 and 8respectively, are rotatably. mounted within the casing 5, and preferably at a point adjacent the opening 6 thereof. The shaft 8, conveniently mounts a suitable contact surface 9, adapted to bear against the face of a drum 10, secured to the shaft 7. 1

'A crank 11 is rigidly secured to one end of the shaft 8, and serves to permit a rotation of the .same, which rotation will obviously be transmitted to the drum 10' mounted upon the shaft 7. In this connect1on, 1t is to be noted that the engagement provided between the crank 11 and-shaft 8 may be in the nature of a pawl and'ratchet connection 12.

Afurther shaft 13, is positioned conveniently in the rear of the casing 5, and serves to rotatably mount a roll of material 14, of.

any desirable character, the end of which extends between the contactsurface 9 and I drum 10, and has frictional engagement with these members, so that a feeding of the end portion of the roll 14 will be effected upon a rotation of the crank 11.

In this connection it is to be noted that the' contact surface 9 may conveniently include a series of circumferentiallyextend- .ing grooves in which the teeth of the combing 15 may extend. This combing serves the purpose of disengaging the paper from the contact surface 9, should the same adhere to this surface due to static electricity, or for otherreasons.

A bafiie member 16. may the drum 10, and project into a groove formed in the outer face of the same to prevent any also co-act with adhering. of the paper to this latter memher.

It is now to be noted that the drum 10 is provided with a cutout portion 17, and a single or plurality of spring aprons 18.have one of their ends attached to the drum, their PP tQ end being provided with teeth 19,

' which latter lie in the position of the parts illustrated in Figs. 1 and 2, within the cutout portion 17.

Thus assuming that the parts are in the position illustrated in Fig. 2, it will be appreciated that a rotation of the crank 11 will result in a feeding of the strip of paper through the opening 6for a distance corre-. sponding to the circumference of the drum 10. This feeding operation may be continued, until the parts are in the position illustrated in Figs. 1 and 2. In this position the spring aprons 18 will be retained in position within the cutout portion 17 due to the tension exerted by the contact surface 9 against one of the faces of the paper, and consequently against the spring apron.

Further, upon a-rotation of the crank 11 being effected, the teeth offree end of the springs or spring aprons 18 will move beyond this point, which will permit the springs to snap to the position indicated in Fig. 2, at which position it will be appreciated that the sheet 1 1 has been completely severed from the roll.

In this connection it is to'be noted that the initial severance takes places in the position indicated in Figs. 1 and 3, in which the teeth 19 are extending into the grooves of the contact surface 9, and consequently perforating the paper, which may thus be read ily severed upon the snapping action aforedescribed taking place.

Thus I have provided a machine which may be utilized to dispense or vend strips of material of predetermined lengths, it being understood that the material will not have to be initially perforated, thus permitting a saving on two points, to wit, the utilization of a roll of material, and secondly, the necessity of having to provide perforations through the material to permit of the severance of the strips.

Obviously numerous modifications of structure might readily be resorted to witl1- out in the least departing from the spirit of my invention, which I claim as 1.'A dispensing device, including a pair of rotatable shafts, a drum secured to one of said shafts, means presenting a contact face forming apart of the second of said shafts, said drum being formed with'a recessedfportion, a spring having'one of its ends attached to said drum, teeth secured to the opposite end of said drum, said teeth being adapted to lie in said recessed portion, and to'engage a sheet of material interposed between said drum and contact face,th'e free end "ofsaid' spring being adapted to swing of said drum.

outwardly and to cause a severance of the strip of material upon said drum being rotated to a point at which the free end is clear of the contact face.

2. A dispensing device, including a pair of rotatable shafts, a drum secured to one of said shafts, means presenting a contact surface attached to the second of said shafts, and being adapted to engage the face of said drum, and resilient means attached to said drum, perforating means forming a part of said resilient means, whereby a sheet of paper interposed between said surface and drum will be directly perforated, and upon a further rotation of said drum will be com: pletely severed and thrown clear of said drum at a speed greater than the rotation of said drum. r

3. A dispensing device including a pair of rotatable shafts, a drum secured to one of said shafts, means presenting a contact sur face attached to the second of said shafts, and resilient means attached to said drum, perforating means forming a part of said resilient means, whereby a sheet of paper interposed between'said surface and drum will be directly perforated, and upon a further rotation of said drum will be com-' pletely severed and thrown clear of said drum at a speed greater than the rotation i. A dispensing device, including a palr of rotatable shafts, a drum secured to one of said shafts, means presenting a contact surface attached to the second of said shafts,

said contact surface being formed with a plurality of annular grooves, and bearing against the face of said drum, and resilient means attached to sald drum, perforating means forming a part of said resilient means, whereby a sheet of paper interposed between said surface and drum will be completely severed and thrown clear of said drum at a speed greater than the rotation of said drum.

5. A dispensing device, including a pair of rotatable shafts, adrum mounted upon one of said shafts, means presenting a con tact surface mounting the second of said shafts, a resilient apron having one of its ends secured to said drum,teeth forming a part of said apron adjacent its outer end,

said teeth being adapted to extend into annular grooves forming a part of said contact surface, and cooperating with the same.

to produce a. perforation and severance of a sheet of material interposedbetween said.

drum and contact surface.
